That's funny I was reading an article about this stuff last night. It seems fantastic.
The .308 kits contain 75 bullets of five different levels of polish conveniently numbered 1 through 5 in a neat plastic container. I followed the instructions with only one exception. The manufacturer wants you to fire 50 of the bullets (10 of each level of polish) and use the 25 "bonus" bullets (five #3, ten #4 and five #5s) later if accuracy deteriorates.
In conclusion, David Tubb's Final Polish System improved the accuracy of the Scout from 4.44" to 2.67", or 39.83%. It improved the RemingtonM700's accuracy from 1.61" to 0.99", or about 38.5%.
Finding: For $35 per weapon, this produced an exceptional accuracy improvement.
After reading this article I have plans to use it soon.
